LIFE RAFT.

Application filed January 16, 1913.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in Figure 1 is a plan view structed in accordance with this invention. Fig. 2 is a side view thereof with a portion broken away; Fig. 3 is an end view with a portion broken away and one section shown by dotted lines in a position as being opened; and, Fig. 1 is a detail View of one of the hinged bolts.

In these drawings 10 indicates a series of metal cylinders tightly sealed and provided with suitable air pump connections 11 through which they may be tested by air pressure. The metal cylinders are contained between a pair of frame work sections substantially identical in construction so that it is immaterial which section is uppermost when the life raft is launched. Each frame section comprises a series 0 parallel slats 12 extending lengthwise of the raft and secured by screws or bolts to a series of parallel carlines 13 extending crosswise of the raft. The rectangular frame sections thus produced are securely held together with the metal cylinders between them by means of hinged bolts 1 1 passing through the ends of the carlines and also through the middle of the end carlines and some of the intermediate carlines. Each of these hinged bolts is formed of two members pivotally connected together with a pair of nuts 15 threaded on their ends by which they are clamped to the frame sections. The pivotal connection between the bolt members is formed by means of a rod 16 extending the full length of the raft and passing Specification of Letters Patent.

through the pivot eyes of the series of hinged bolts 14: at :the two sides of the raft and through the middle of the raft. These rods 16 are held in place within the eyes of the hinged bolt members by having nuts 17 threaded on their ends. One member of each hingedbolt is further provided with an ear carrying a ring 18 through which .a festooned entirely around the raft with a SGlIlG float 20 at eachblght thereof.

The carlines 13 are so spaced apart as to 'just receive between them the cylinders .10. the ends of the cylinders abutting against the carlines and theslat-s 12 bearing agalnst -thecylinders atdiametricallyopposite parts 3 thereof.

To further rigidly hold the cylinders inplace there are slats 21 secured by bolts or screws to the carlines 13 on the inner sides of each frame section and like the slats full length of the raft. These slats 21 are positioned to engage the cylinders and are preferably beveled to fit the walls of the cylinders as shown in Fig. 3 and serve to prevent lateral displacement of the cylinders.

Oar locks 22 are adapted to have their shouldered stems pass through openings 23 provided for them in the slats 12 and 21 at the sides of the raft and similar devices 2a with longer stems to reach through from top to bottom of the raft and provided with closed loops on their ends to receive oars for steering purposes are adapted to fit in openings 25 provided for them in slats 12 at the ends of the raft.

The corners of the desirably protected by means corner plates 26 to prevent ends of the wooden strips handling of the device.

A life raft constructed in accordance with this invention may be readily opened up for and repainting by simply removing two of the metal rods 16 by unscrewing the nut from one end thereof and sliding the rod lengthwise out of the eyes of the hinged bolt members. l/Vhen this is done the upper frame section may be swung upwardly as shown by dotted lines in Fig. 3, giving free access to all parts of the device for testing the cylinders and repainting them and the other parts. Furthermore the construction is such that each cylinder fits within pocket-like seats in raft frame sections are of bent metal injury to the during rough said life-line being the frame sections from which it cannot be dislodged even though subjected to great stress when the raft is aunched.

hat I claim as new and by Letters Patent is:

1. A life raft, comprising float members, frame sections having the float members positioned between them, hinged bolts with removable pivotal pins connecting the frame sections together whereby the removal of the pivotal pins from some of the connecting bolts permits one frame section to swing upon its hinge connections with the other frame section to release the float members.

2. A life raft, comprising float members, frame sections having the float members positioned between them, hinged bolt members secured to the frame sections and provided with interfitting eyes and removable rods passing through the inter-fitting eyes of the bolt members to hold the frame sections together.

3. A life raft, comprising rectangular frame sections formed of parallel lengthwise slats secured to parallel crosswise carlines, some of the slats being on the outer side of the carlines and other slats being on desire to secure the inner side of the carlines, cylindrical float members positioned between the frame sections with their ends fitting between the carlines and their sides bearing against the outer slats and positioned between pairs of the inner slats, the inner slats of each pair being spaced apart a distance less than the diameter of the float members to confine the float members between the frame sections as well as to prevent their lateral movement, and removable means for connecting the frame sections together.

4. A life raft, comprising a pair of f ame sections, float members positioned betw en the frame sections, hinged bolt members connected to the frame sections and having interfitting eyes, rods passing through the interfitting eyes of hinged bolt members to hold the fame sections together, rings on the bolt members of one frame section, and a life line passing through said rings.

In testimony whereof, I aflix my signature, in presence of two witnesses.
